SPECIFICATION forming part of Letters Patent No. 293,260, dated February 12, 1884.'.

A kApplication filed Julyr 23, 1881. (No model.) i I w To all whom it mail concern,

Be it known that I, .LIMEs I-I. MANNY, residing at Chicago, in the county of Cook and State of Illinois, andla citizen ofthe United States, have invented new and useful Improve.- ments in Apparatus for Heating and Ventifull description, reference being had to the accompanying drawings, in whichM i Figure l is a plan. Fig. 2 is a section at line .fr of Fig. 1, looking toward the furnaces, and at that side of the room in which the hotair lines are placed. Fig. 3 is a vertical crosssection through the Ventilating-line, showing the main smoke-pipe in such flue. Fig. 4. is a section at line y of Fig. l, showing that wall of the building opposite to that shown in Fig. 2. Fig. 5 is the same as the lower part of Fig. 2, enlarged, showing in elevation one side of the. two furnacechambers, with 'the chain which operates the valves D and V. Fig. 6 is an enlarged detail, showing, among other things, smoke-pipes extending to the furnaces. Fig. l7 is an enlarged detail, being chiefly a horizontal section of the parts shown, showing the connection of the circulatingpassages Fig. 8 is a vertical section at line x of Fig. 7. Fig. 9 is a vertical section through the furnace-chambers, with a furnace in one only of such chambers, at line w, Fig. 10. Fig. 10 is a detail, being a horizontal section showing the air-ducts leading to the furnace chambers. Fig. 11 is a detail, showing howthe endless chain a, which is connected with t-he registers G, operates the valves J. Fig. 12 is a vertical sectional view of a building showing my invention applied Fig. 13 is a vertical section taken on the right-hand half of Fig. 4, and illustrating, on an enlarged scale, the two registers and means for simultaneously operating the same. Fig. 14 is a side view of one of the ventilators enlarged, and Fig. 15 is a cross-section thereof.

The obj ect of'my invention is to provide improved devices to be used in heating and ventilating largebuildings. In cold weather much more heat is required than in mild weather.

withcold-air ducts in such manner that the cold air can be admitted to both or to only one 5o of such furnaces, as maybe desired. I also provide a hot-air chamber in connection with i said two furnaces, having a valve, so constructed that either furnace may be used for supplying heat tothe entire building, if desired, or for supplying heat to a portion only of the rooms of the building, if desired. I also operate the valve controlling the admission of air to the furnace-chambers :and the valve in the hot-air chamber simultaneously. 6o

I further provide an air-passage from each nace-chambers, within'each of. which is to be 75 placed a furnace of any suitable construction. In some of the gures the furnaces are not represented at all, and in some of them a furnace is shown in one of the chambers only.

N N', Fig. 6, represent two furnaces, one in 8o each of the furnace-chambers A A. 9 one furnace is shown, and in Fig. same furnace is indicated.

`B B are two cold-air ducts leading from the outside of the building to a small chamber, C, 8 5 which chamber communicates with both of the furnace-chambers by means of passages 'P F', Fig. 10. In this chamber C is a valve, D,

In Fig.' 10 `t-he so arranged that it can be used to divide the chamber Cinto two parts, directing the cold 9o air from the duct B to the furnace-chamber A andthe cold air from the `duct B to the furf nace-chamber A. .Said valve can also be used to close the passage from the chamber C to either of the furnace-chambers, so that the cold air from both ducts B B will pass to either ofthe furnace-chambers atpleasure. There is a wall, W, between the two `hot-air chambers A A, but this wall does not extend to the top of these chambers; and there is a valve, V, at the top of this wall, which wall and valve, when the valve is closed, separate the furnace-chambers from each other. so that then Veach furnace has a separate hot air chamber, but when the valve is open there is 4a common hot-air chamber for both furnaces.v

The hot air is conveyed from the furn/acechambers to the rooms through iiues U and passages in the usual manner.

E is a Ventilating-shaft.

F are smoke -pipes leading from the furnaces to a common smoke-pipe, F, located in the Ventilating-shaft E.

G are ventilatingregisters, one for each room', controlling the passage 'of air from the rooms to the shaft E.

H are passages, one for each room, leading to and opening into one of the cold'air ducts B B. The passages H open, respectively, in-

l to the cold-air ducts B B, (see Fig. 7,) and at the point of junction of the passages and ducts are located pivoted valves J, which are capable of being turned so that the air-ducts B B and passages H communicate with cach other, and the air will then constantly pass -from the rooms through the passages Hto the cold-air ducts, or such valves can be turned to cut off communication between the passages H and said duets. The Ventilating-registers G, which control the passage of air to the Ventilating-shaft E, are in the several rooms over 'each other and are connected with each other, and also with one of the valves J by means of a single chain, a, so that they can all be closed or opened together. This Ychain passes over the pulleys at the top andl bottom.

K are registers over the openings through which cold air passes from the several rooms into the circulation-ducts H. These registers are also operated by the chain a., as shown in Fig. 13; but if not connected with such chain the passage of air from the rooms to the coldair duct can be controlled by the valves J. The slats of the ventilator K are vertical, as usual, and are arranged to move in a direction opposite to the direction in which the slats in G move, so that one closes while the other opens.

lL are registers which control the admission of hot air to the several rooms.

e are valves which control the passage of hot air from the furnace-chambers. They can be operated in any suitable manner. As shown, cold air from without is supplied to the furnace-chambers through the openings M M', which communicate respectively with the passages B B.

c, Fig. 5, is a crank connected to the valve V. b is a chain connected with the crank n. This chain is also connected with the valveD which controls the air-inlets to the furnacechambers, so that both of these valves V D can be operated simultaneously, as shown in Figs. 5 and 6.

'the rooms to the furnace-chambers` through The operation is as follows: If the valve V be closed and the valve D be arranged in; the

middle of the chamber G, as shown in Fig. 5, and the valve J be arranged so as to close the passages H, opening into the cold-air ducts, cold air will pass from outside the building to each of the furnace-chambers, and hot air will be supplied from each furnace-chamber to that part ofthe building with which the hot-air ilues leading therefrom communicate. At the same time the ventilatingregisters G will be open, permitting the escape of the foul air from the rooms to the outsidev of the building up through the Ventilating-shaft. When heating the building while the rooms are unoccupied, thev Ventilating-registers G may be closed, and the valves J may be arranged so that the passages H, openingV into the outside cold-air ducts,will be opened, and these cold-air ducts will be closed by these valves J. Then cold air cannot pass from outside to the furnacechambers, but air will be supplied to such chambers from the rooms through the circulation-passages H and ducts B B. arrangement of the registers G and valve J can be simultaneously effected by means of a single chain, as before stated. Vhen the rooms are occupiedthe registers G can be opened, and the valves J also, to admit cold air from outside, and the passages H may be closed. In mild weather the valve D may be arranged so as to close the cold-air openingto one ofthe furnace-chambers, and at the same time the valve V maybe opened, so that there will be but-a single, large hot-air chamber.

This

This arrangement will be used when only one v furnace is in use, and then the hot air from this one furnace will pass through the proper ilues to all the rooms with which the hot-air pipes from the two furnace-chambers are con nected.

There are many advantages resulting from theA construction described, among which I will mention the following: It is much easier Ventilating-registers Gbe open while the building is being heated before being oeeupied,there will be a constant escape of Warm air from each room, causing a great loss of heat and requiring much more time to bring the roomsto the proper temperature. By closing these registers G and arranging the valves J so that they close the outside cold-air ducts, as before described, the cold air from the several rooms tween the' chambers, in combination with ducts arranged to supply cold air either to both or to one-of the said chambers, whereby the furnaces can be used together, each heating a separate part of a building, or either of the furnaces can be used alone for heating the Whole building, substantially as and for the purposes specified.

2. The oireulatingpassages H, one connecting with each room, in combination with separate cold-air ducts B B', opening, respectively,

into the passages, and Valves J, arranged, re-

s'pectively, at the junction of the passages and ducts and capable of adjustment to establish communication between the 'said passages and duets and cause the air from the rooms to ilow through the coldair ducts, substantially as described.

3. The combination of the Ventilating-registers G, the circulation-passages H, and valves J, controlling both the cold-air duets and the passages H, all adapted to be operated simultaneously, substantially as and for the purposes specied. Y

4. Avalve, V, andavalve, D,control1ing the air-inlets to the furnace'ehambers, said Valves being` connected together, so` as to be simultaneously operated, in combination with two furnace-charnbers, .A A', andair-ducts B B', substantially as and for the purposes specied.
